Ms. Garcia demonstrates heat transfer for her students by placing an ice cube in a glass of warm water and stirring the water with a straw. Which statement below best describes what is happening?

A. The total thermal energy of the glass of water increases.

B. The cold from the ice cube moves to the water in the glass.

C. The ice cube melts as the water reaches thermal equilibrium.

D. The heat from the water moves to the surrounding air, melting the ice cube.

C. The ice cube melts as the water reaches thermal equilibrium.

Step-by-step explanation:

I put an ice cube in a glass of warm water and it melted.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

b. x- 48 =120
